A good interview process covers average-level coroutine concepts like scopes and lifecycle, along with Android basics such as activity lifecycle, intents, UI components, and ViewModel usage for effective app architecture.

Core Concepts: Focus on understanding and implementing key data structures like arrays, linked lists, stacks, queues, hash maps, trees, and graphs. Algorithms: Review sorting algorithms (e.g., quicksort, mergesort), searching algorithms (e.g., binary search), and understand time and space complexity (Big O notation).
